Write Cache Efficiency Topic is solved
Re: Write Cache Efficiency
FYI - with 60s Deferred Write and relatively small cache I consistently see a 24-26% reduction in real writes to SSD. Never experienced a recovery problem following system crash. Works a treat.

Re: Write Cache Efficiency
I cant see how if the OS has requested a 4K write that PrimoCache would write, in my case, 32 K..because it would kill the ntfs disk structure.
If a request to write a 4K block happens, and the very next block (cluster) of 4k on the disk belongs to another file...then a 32K write would destroy whatever file lived next to it.

Re: Write Cache Efficiency
PrimoCache operates at the block level is aware of adjacent block contents. Whether 'rewrites' always occur or Primo is smart enough to only write changed blocks is for support to address. Personally I'm not worried about it but I suppose it could be an issue in edge cases that combine large soft block size with massive small, non-sequential writes.
